The comic and Oscar-winning actor, 60, married graphic designer Susan Schneider at the luxurious Meadowood Resort in the Napa Valley town of St. Helena, Calif., on Sunday. Rumored guests at the bash included Steven Spielberg, George Lucas and Billy Crystal, among others.

In the days leading up to her wedding, Schneider, who heads up graphic design firm Critical Eye Design, told the San Francisco Chronicle she was "so excited and so thrilled" for her big day.

It's the third marriage for the "Good Morning Vietnam" star who finalized his divorce with second wife Marsha last year. He has three kids: son Zachary, 28, with first wife Valerie, and daughter Zelda, 22, and Cody, 19, with ex Marsha.

According to British paper The Guardian, he met Schneider shortly before undergoing heart surgery in mid-2009; she nursed him back to health at his L.A.-area home.

Daughter of the groom Zelda Williams tweeted about the big Napa weekend. "Let the wedding madness begin!" she wrote Saturday. "Dad just called @RobertKazinsky and @ShannonCollis my hetero-lifemates at the wedding," she cracked of two male pals.

"Just realized my tweets have probably been misconstrued. No, it's not my wedding, haha. Thanks for the congratulations regardless. The wedding festivities rage on but my tired feet are done. Think it's time to lay in the tub, eat m&m's and write."
